Txoj kev tsim kho kom raug ntawm refractory castable

Niaj hnub no, cov khoom siv hluav taws xob sib sib zog nqus tau dav siv los ntawm cov neeg siv feem ntau, thiab kev siv cov khoom siv hluav taws xob kub-insulating refractory tau tsim los ntawm cov khoom siv hluav taws xob tsis zoo ntawm cov khoom siv hluav taws xob hluav taws xob. Yog li yuav ua li cas siv refractory castables kom raug hauv kev ua haujlwm txhua hnub? Hnub no kuv yuav coj nej mus saib:

1. Lub refractory castable yog tsuas yog tov los ntawm ib tug tov khoom nyob rau hauv lub lag luam tiag tiag, thiab phau ntawv sib tov yog txwv tsis pub. Thaum tsis muaj lwm txoj hauv kev, kev sib xyaw ua ke yuav tsum tau txais yuav. Tab sis kom huv si hauv av, castable yuav tsum tau ntxiv nrog ib coagulant. Tus nqi ntawm coagulant yog 3%. Yog tias nws nyob ntawm qhov chaw, koj tuaj yeem ntxiv 5% sib tov sib npaug thiab tom qab ntawd ntxiv 8% PA80 kua nplaum rau kev sib xyaw kom nrawm thiab siv tau sai, kom ntseeg tau tias nws tuaj yeem siv tsis pub dhau 10 feeb.

2. Ua ntej pouring, thawj lub tsho tiv thaiv cov thauj tog rau nkoj nrog ib txheej ntawm asphalt thiab xim. Thaum lub thickness ntawm pouring yog nyob rau hauv 250 hli, nws yuav tsum tau poured mus rau lub thickness ntawm ib lub sij hawm, thiab vibrate kom txog thaum nws yog tag nrho compacted.

3. Siv cov khoom sib tov los sib tov cov castable, ncuav lub castable rau hauv lub tov khoom ua ntej, thiab ntxiv 5-3% ntawm condensate. Kho raws li lub sij hawm hardening. Feem ntau, thaum kub yog ≤25 ℃ nyob rau lub caij nplooj zeeg, koj tuaj yeem ntxiv 5%. Piv txwv li, thaum qhov kub ntawm qhov yuav tsum tau ua yog ≥30 ℃, koj tuaj yeem ntxiv 3%. Ncuav mus rau qhov chaw teev tseg kom txog thaum ua tiav.

4. Thaum nrum lub teeb-yuag thiab kub-resistant castables, nws yog ib qho tsim nyog los ntsuas qhov zoo ntawm lub ladle thiab tus naj npawb ntawm load-bearing lub sij hawm rau ntau zaus. Seb nws yog crane high-temperature castable ladle lossis portable ladle, check it every 2 months 1 Second, check the important parts for cracks, deformation, o, etc.

5. Cov pwm yuav tsum tau muab ntxuav ua ntej lub nti pwm, thiab cov pwm yuav tsum tau coated nrog ib txheej ntawm cov roj thaum lub nti pwm.

Cov saum toj no yog txoj kev raug ntawm refractory castable tsim, Kuv vam tias nws yuav pab tau koj thaum siv cov khoom siv refractory castable no.
